US Secretary of Commerce Howard Lutnick has claimed a trade deal between Britain and America would have taken three years had President Trump not been in power.

Speaking to reporters, Lutnick said the major agreement took Trump just 45 days to conclude.

Trump watched on as his Secretary of State heralded the deal that works “exceptionally well” for America.

“We feel really good about the deal, you’ve heard the prime minister, he feels really good about the deal”, he said.

“We started at 10 per cent and we ended at 10 per cent [tariffs] and the market for America is better and this is a perfect example of why Donald Trump produced liberation day.

“People don’t understand he gets things done. This would have taken Jamieson [Greer] and I three years maybe. This took President Trump 45 days.”
